NOTE: URLs must not contain spaces, letters with a diacritic
placed over them, aka as caron (č, š, ž) and some other characters. Instead of a space
either the "+" sign or the "%20" characters should be used.

What to do? In the base parameter, enter either the
library code or cronym or a word from
the name of the library or a database. If the word is contained in the
names of several libraries, a list of these libraries will appear (example
3).
The best way to access individual libraries within COBISS is to use a unique
data within the COBISS system, i.e. the library's code (examples 1 and 2).
